There are measures to help ensure sheep predators have a harder time killing your sheep while encouraging them to seek other sources of food.
Becoming familiar with the various sheep predators you may deal with will give you a heads up on what to expect.
Use a livestock guardian animal. This is another animal who has developed an affinity for sheep and a willingness to defend the group. Livestock guardian dogs are the most common among sheep producers. Other guarding animals include llamas and donkeys.
Good fencing can also be a deterrent. Our perimeter fence is five strand high tensile wire, four of the wires are electrified. We have witnessed a coyote refusing to cross the five wires even under human pressure. As soon as the four legged reached the neighbours property, where it is only a two strand cattle fence, he made his escape.
Electra-netting and field fence (page wire) are other types of fencing commonly used to deter predators, although both are expensive. We have never seen a coyote inside of our field fenced paddocks but foxes slip through it easily. We utilize Electra-net for cross fencing on pasture. It is very portable and works decently in deterring animals.
Building a flock with strong flocking behavior will serve in developing individual animals who know how to graze as a flock. This flocking behavior offers each individual ewe and lamb the very protection they need to ward off sheep predators.
Checking the flock at least once a day can deter predators. You leave a scent trail and are a visible presence on a regular basis. At the very least checking often will give you an early heads up if predators are moving in.
Remove the carcass of dead animals. Leaving carcasses on pasture or at the yard attracts unwanted hunters and scavengers to the area. Once started there, it is a small leap to the live ones nearby.
Similarly, feed your guardian dogs away from the fence-lines so as not to attract unwanted guests.
Leaving lambs with moms until they are weaned naturally or sold to market allows all animals to benefit from the safety of their numbers.
It also allows time for lambs to learn important survival lessons. The youngsters learn how important it is to stay in contact with the flock. If you're keeping replacements ewe lambs this will serve you well in the long term.
Checking animals often but handling and housing them less goes hand in hand with a grass based flock. When handled less and without buildings to shelter in ewes tend to stay alert to dangers and maintain their savvy survival skills.
Time the lambing as nature intended it. In the early summer there is an abundance of wildlife on our land. Therefore, we are lambing during a time when the coyote's, our main sheep predator, needs can be met with easier food choices. By this time the coyote is through birthing their own young so their demand for food is becoming less.
Multi-species graze. Bonding and grazing sheep with cattle can lead to added protection for the flock. The key to this is bonding the livestock to one another first.
While no single method will be the be-all-and-end-all answer, all of these measures add up. A combination of methods can go a long way to ensuring adequate protection from coyotes and other sheep predators.
